r In my co-pending application, Serial No. 385,243, filed August 12, 1929, I illustrat.ed

and described an apparatus for positioning;

cans so that flanges of the were passed under a hopper, a continuous stream of liquid was passed therefrom'and the upper outward annular into said cans, spilling being prevented by the overlapping flanges. q The type of machine'to which this invention has been applied is illustrated and described in my Patent Nos. 1,828,167, granted October 20, 1931, and 1,818,780, granted August 11, 1931, although the invention may 0 be applied to other machinery withequally good results.

g The object of this invention is to provide mechanism whereby a predetermined quan-- tity of liquid may be served into each can when, and only the same is applied is operating.

A further object, conversally stated, is to provide a mechanism which insures the serving of liquid to the cans when the machine is being operated. i 7

According to the invention the liquid sup; ply mechanism for introducing a predetermined quantity of liquid into successivecans is provided with a regulating'valve and with a valve which controls the flow of liquid, and the latter valve is coupled with the operating lever of a can filling machine so that liquid is admitted to said cans during the operation of the can filling machine, and the supply is entirely cut off when the can fillingmachine is at rest. 7

The drawing illustrates an embodiment of the invention and the views therein are as follows: 1

way in the valve 16, the gate valve 21 will I permit the complete passage of the liquid from said regulating valve intotheliquid directing box 14 when said gate valve 21 is opened.

On the other hand, regardless of the posi tion of the lever 17 no liquid may ever pass down through the gate valve 21 into the liquid directing box 14 when the valve 21 is closed.

Nor isvit ever' desired that liquid should pass down into the cans 9, except when the entire can filling machine, which I. shall designate A, is in operation. It, therefore,

follows that when the 'shipperhandle. 8fis' in the position shown in Figure 1, the gate valve 21 is entirely closed and no liquid V flows through pipe 13 into the liquid direct ing box 14, although the regulating valve16 is open for the passage of a predetermined quantity of liquid,whenever an outlet is pro- J vided through thegate valve 21'.

In order to start the machine it is neces-' for any reason, is

the direction of the admission of the liquid through the pipe box 14 is immediately discontinued. 7

Of course, the liquid supply .mechanism for can feeding machinery illustrated may be modified'in various ways without depart- 6- ing from the inventionherein' set forth and hereafter claimed. v V

The invention is hereby claimed as follows:

' In combination with a canfilling machine having an operating handle, of means comprising a fluid pipe for supplying liquid to said cans and having a gate valve in said pipe for opening and closing the passageway for'said liquid, and means connecting said gate valve with the operating handle ofsaidmachine whereby. the gate valve is fully opened when the machine isoperated and totally closed'when the machine is stopped.
